The latest version of firefox 87.0 does not allow the drop down arrows or autofill to work either on webpages or in firefox. For example in the section "which topic best describes your question?" it would flash the drop down menu but not open it nor allow me to select an option since it opened and closed so quickly. I was able to up the keyboard arrow keys to scroll thru in this case. Same for autofill-addresses, passwords and so forth. The option flashes on the screen for a milisecond and then disappears. Sometimes the arrow keys on the key board will work, other times nothing works.

This only happens on firefox, not on Chrome.
